It's one of the places where I think children's fiction gets an unfair advantage over the rest of us. (I'm not trying to imply you get it all easy
.) You see it too in stories like Harry Potter, where the names presented in the first book (while the story was still quite young in character and nature), we get names that lead us to impressions of the characters, also the various school houses, the magic words, and various other features of the story. They were fun then, just part of reading a kid's tale, and by the time the stories grew up we were all used to them and didn't really notice that many of them were, in some respects, a little childish given the more mature context at the end. (I still marvel at how smoothly she managed the transition.)
